In the old StackExchange (for some incomprehensible reason) it was possible to have multiple users with exactly the same username. During the import of the old data into the new system those duplicate users needed to be made unique, which explains why there are now users with numbers after their names.

We will be happy to help users get back all their identifiable reputation points, and going forward the reputation system should be consistent and stable. The main issues are directly related to ambiguities in the old StackExchange data dump.

Thanks for the quick reply. Last year, I asked a women on this site why she posted such an awesome answer as a comment (because I couldn't up-vote her/give her points for the answer). She said competing for points is a guy thing. (Maybe she was right!)

Hi @dzone, my account was linked to an email address that is no longer active. I've logged in under the very first account that I used, but I would like to get my old account back (@Thumper) Please let me know what I need to do. Thanks!
